Proline heating thermostat
61 / 123
Each program begins with the segment "Start". It defines at which temperature Segment 1 is to contin-
ue the program. It is not possible to specify a time for the Start segment. Without the Start segment,
Segment 1 would be different depending on the bath temperature at the start of the program.
For heating thermostats the start temperature must be set above the actual bath temperature during
program start together with a sufficient tolerance to allow reaching the set temperature without cooling
(especially if no additional cooling is available). Testing and watching the process with "Graphical Dis-
play" (
7.9).

Change segment time or tolerance (
Section 7.10.4)
The field tolerance (refer to the above program table and the graph below):
It facilitates exact conformance to the dwell time at a specified temperature. Segment 1 is not
processed until the bath temperature is within the tolerance range
, so that the ramp (Segment
2) starts delayed at
.
A tolerance range which is too tight can however also cause undesired delays. In particular with
external control the range should not be chosen too tightly. In Segment 5 a larger tolerance has
been entered, so that the desired time of ten minutes is maintained even with settling action
.
Only flat (slow) ramps should be programmed where necessary with a tolerance range. Steep
ramps which lie close to the maximum possible heating or cooling rates of the thermostat may be
severely delayed by a tolerance range that is too tight (here in Segment 2)
